and a metal whereby the strength of the metal is combined with the attractive appearance and comfortable qualities of the non-metallic member.

One of the leading objects of the present invention is the provision of an improved' frame for an ophthalmic mounting which shall embody the strength and durability of an ordinary metallic construction together with the ornamental appearance and the cushion or lens protecting features of a noumetallic frame.

Another object of the present invention is the provision of an improved construction of frame wherein improved means`is used for' uniting the metallic and non-metallic parts. With the above and other objects in View the\invention consists in the novelfeatures of construction and the combination and ar- `lili rangement of parts herein more fully set forth, pointed out in the claims and shown in the accompanving drawings, in which FigureIi is e? front elevation of a pair of spectacles constructed in accordance with my invent-ion. y

Fig. II is a longitudinal sectional viewl at the meeting ends yoieaoh frame.

Fig. III is a transverse sectional view taken through the frame.

Fig. IV 1s a transverse. section of the blank from which the metallic trame is formed. Fig. V is a transverse sectional view illustrating another form ot the invention.

Fig. VI is a similar view illustrating still another form of the invention.

Fig. VII is a transverse sectional view of the metallic )art before boing pressed into the non-metallic part.

Fig. VIII 'is a transverse sectional view of the non-metallic part of the frame.

Fig. IX is a transverse sectional view taken through the trame, illustrating another form or the invention.

Fig. X is a,similar View illustrating still another t'orm ot' the invention.

Fig. XI is a transverse section of the trame illustrating another modified form of the` invention.

Referring now more particularly to the drawings in which the several parts are designated by the various reference characters the numeral l indicates the non-metallic rim of my improved mounting the inner 'face of whiehis provided with the substantially arcnate/recess as indicated at 2 and extending at afn angle from each side wall ot the recess are the annular grooves El. The metallic trame which is indi fated by the numeral -l is disposed within the recess 2 and provided with the angularly extended annular flanges 5 adapted to. be disposed within the ,ffrooves 3 iinorder to retain the metallic trame within the recess 2. It will be no'ted that the central portion of the metallic'iirame is of arcuate formation to receive the edges of the lenses 6 whereby when the frames are fastenedV together at their ends/the lenses will be securely held in place.

In the construction of, the metallic part of in v improved trame a' blank of material isused such as that illustrated in Fig. IV and bent into U shape form as illustrated in Fig. VII. In placing the metallic part rin the recess 2 within the non-metallic part the annular flanges 5 of the l) shape member are inserted in the grooves 3 and the intermediate portion of the member bent to conform to the shape of the recess as illustrated in Fig. III. On the other hand the intermediate portion of the U shape member may be bent into U shape form as illustrated. in Fig. V before the same is engaged with the non-metallic member.

In Fig. VI I have illustrated another form of the invention wherein the annular flanges of the' U shape member are corrugated as shown at 8 so that when the saine 1s pressed into the non-metallic material it ln Fig. iii l have illustrated still another form ol the invention wherein the intermediate, portion of the metallic member is provided with a centrally disposed annular rib 9, which is normally disposed Within a centrally arranged recess formed within the central portion of the recess 2 and is adapted to retain the metallic rim Within the nonmetallie portion. It will be readily understood that this annular rib 9 can be co1- rugated in the same manner as the flanges as is clearly illustrated in Fig. X anddisposed within a sin'iilar recess or groove l0 whereby when the non-metallic material is put under pressure it will. be pressed into the grooves of the (,-frugations and securely retain the metallic member `within the recess 2.

ln Fig Xl l. have illustrated the annular rib 9v in connection rv'itb the side flanges 5 wluereby the metallic part of the frame will he seclnely retained Within the non-metallic part. ln this form of the invention the rib may be used in either a smooth or in corrugated form. From the above description taken in minneetion with the accompanying drawings it will be readily apparent that I have provided a novel spectacle frame formed by the combination ot' two different materials such as shell or zylonite and a metal whereby the streiigth ot' the metal/is combined. with the attractive appearance and comfortable qualities of the non-metallic member. y

In the drawingsfw mounting is illustrated it will. be noted that suitable temples 12 are provided and the frames arecentrally connected by the nose` which my improved bridge ll as illustrated lin Fig. Extending out from the metallic part of the frame are the lugs 13 detachably connected by means of the screw la whereby the lenses in the frames can be readily exchanged when desired. claim: l l. A lens frame including an outer nonn'letallic member, having an annular recess, and further provided with grooves communicating with said recess, a metallic member disposed within the recess, flanges projecting outwardly from the metallic i'nember and engagiilg Within the grooves and nleans for securing the two members together.

2. A lens frameinchiding an outer nonmetallie nien'iber, having an'annular recess, and further provided with grooves communicating with said recess, a metallic member disposed Within the recess7 flanges projecting outwardly from the metallic member and ei'igaging Within the grooves7 said flanges being provided with corrugations and means tor securing the two members together.

3. A. lensframe including anv outer nonmetallic member having grooves therein, a metallic men'iber arranged Within the outer member and having means disposed Within said grooves to prevent movement of either of said n'xembers with respect to each other` ln testimony whereof l have allixed my signature in. presence of two Witnesses.
